Ammonia, chemical formula NH3, is a caustic (but not toxic) gas at room temperature and pressure but it is easily stored under moderate pressure just as propane is. It is used as an industrial chemical, both directly and indirectly as a fertilizer, and there is a growing movement to use ammonia as a fuel; it is the only carbon free hydrogen carrier we can make and handle with today's technology.

   I've been working in this area for the last ten months and I thought I'd provide a little overview of how the stuff is made and where we need to go next to ensure our food supply and begin the transition to this clean hydrogen carrier as a fuel.
